Love getting new equipment, hate the break-in

@sns I think there is no use to argue with "roadcykler", he knows better than anyone. It is the fact.

Burn-in is real, for sure. But it is in your ears/auditory center. That is referred to as habituation. I challenge anybody to do a blind A-B test with a burnt-in component vs out of the box. Good luck! Re capacitor formation/degradation etc., the question is, does it matter, is it audible?

BTW: null hypothesis in statistical testing is "no difference".

A genuine new, be it OS or current production, signal tube will demonstrate improvement in performance with time, to a point upon which it levels off, relative to initial performance.

@oberoniaomnia  Statistics don't mean doodly-squat.  Did you verify this on Youtube?

@boxcarman Oh dear! 

I'm actually a MINT scientist. Have published in peer reviewed journals using statistics, like breakpoint regressions, Discriminant Function Analysis, various flavors of (M)AN(C)OVA etc. Got my first editorial appointment fresh out of grad school because, as a reviewer, I found a fundamental statistics problem in a ms, based on a dissertation passed by a fully accredited US university [used PCA instead of DFA to show differences between groups, btw. And if you don't immediately see the problem, you know doodly-squat about statistics. But that was clear from the outset anyway.].

No, I don't need YouTube re statistics. Thanks for asking.
